Uart Application - Quectel EG060K Series Hardware Design

the DRX cycle is, the lower the power consumption will be.
Figure 3: DRX Run Time and Power Consumption in Sleep Mode
The following part of this section presents the power saving procedure and sleep mode of the module.

3.1.1.1. UART Application

If the host communicates with the module via UART interfaces, meeting the following requirements will
bring the module into sleep mode.
⚫
Keep MAIN_DTR high (pulled up by default).
⚫
Execute AT+QSCLK=1 command. See document [4] for details about AT+QSCLK=1.
The following figure shows the connection between the module and the host.
Driving MAIN_DTR low will wake up the module. When the module has a URC to report, MAIN_RI signal
will wake up the host. See Chapter 4.8 for details about MAIN_RI behavior.
